* supports DVB/ATSC (but with no analog support). This is targeted at digital only devices.

EM2870 devices include:

* next generation version of the em2870 design - they moved around a bunch of registers compared to em2870/2880 and the chip itself supports two transport streams (although most designs will probably only use one stream).

* [http://mcentral.de/wiki/index.php5/Main_Page mcentral.de wiki] offers alternative, out of kernel, drivers for some em28xx based devices:

** [http://mcentral.de/wiki/index.php5/Em2880 mrec's page on the em2880] ... note: that the information seems heavily tied to devices which utilise a xceive xc3028 tuner ... hence you may also want to read his xc3028 page for related info

Feature Support

No firmware is required for em28xx ICs ... note: though em28xx based devices paired with some tuners will need firmware for the tuner (i.e. there are em28xx based devices paired with a XCeive XC3028 or XC2028 tuner, which require a generic firmware from Xceive).
